o Regexp.PCRE: Do not match the empty string past the end of the input. o Reduced the risk of throwing out-of-stack errors while formatting an out-of-stack backtrace. o Fixed bug that would cause sprintf's %nH to refuse all strings as too long for some values of "n" on some architectures. o Made Process.search_path() aware if Win32 and AmigaOS specifics.
o Fixed bug in Protocols.HTTP.Query that dropped the last byte of a
request if the server did not provide a Content-Type header.
Optimizations ------------- o Fixed Filesystem._Tar.ReadFile to not gobble the whole tar entries into memory at once. o Improve performance of get_cpu_time() on OS X by avoiding a kernel trap to get the ID of the underlying system thread.
